It would better if instead to being sent to global flashcard pile when clicking on flashcards and being sent to a page with all of your flash cards. Somewhere on the page, you can then have the global flashcards page if you really need the feature. I think that people want to study induvial flashcards then a global flashcard app more. If you can already do this somehow, please feel free to correct me .
You may practice any rem’s flashcards only from the upper right Rem Options.
